Question

multiple choice question
almost all bony fishes have
o paired fins but no jaws.
o lungs and swim bladders.
o fleshy fins.
o fan - shaped fins with bony rays.

Explanation:

Bony fishes (Osteichthyes) are characterized by having fan - shaped fins supported by bony rays. Paired fins but no jaws is a feature of some primitive fish groups like lampreys (which are not bony fish). Lungs are not a common feature in most bony fish (some have swim bladders for buoyancy control). Fleshy fins are more characteristic of lobe - finned fish (a small group within bony fish, not the majority).

Answer:

fan - shaped fins with bony rays.
